Appl. No.:

9/480579

Inventors:

Frank S. Grott - Punta Gorda FL

International Classification:

A01G 2500

US Classification:

239 63

Abstract:

The invention is directed to a system for controlling lawn and garden watering by using electronic sensors to detect the moisture in a lawn. A probe determines the soil water content and powers a signaling device which operates switches for either signaling the need for more water or to stop watering to prevent over-watering. The status of the moisture in the soil is indicated by raising a flag or lighting a strobe light for a visual signal.

Appl. No.:

5/584657

Inventors:

Frank S. Grott - Baltimore MD

International Classification:

F24C 300

US Classification:

126 85B

Abstract:

A kit for converting presently used household or light commercial furnaces of the oil or gas type which inefficiently consume unnecessarily large quantities of fuel, to a more efficient mode of operation wherein smaller quantities of fuel are consumed. The kit comprises prefabricated components which can be easily attached to the furnace in such a way that fresh air is brought in from the outside to support the combustion process, and meet the needs of the draft diverter, rather than using already heated and/or humidified air as is done in presently existing systems.
